LIQUID-IMPREGNATING DEVICE.

Specification of Letters Patent.

Patented Oct. 7, 1913.

To all whom it may concern Be it known that we, GEORGE ED ARD HEYL andFREDERICK JOHN ALLEN, subjects of the King of Great Britain, residing atKings House, Kingsway, London, England, and St. Alkmunds, Hermon Hill,Wanstead, Essex, England, respectively, have invented aLiquid-Impregnating Device, of which the following is a specification.

This invention relates to a new article for domestic use which comprisesa layer of material required for the impregnation of a relativelyconsiderable volume of liquid, which layer is inclosed between twoadherent sheets of protective material forming a flat article, thetriple layer being so perforated with rows of apertures as to permit thedetachment with facility of a determined portion of the article from theremainder just as an individual postage stamp can be detached from asheet of stamps.

The nature and purpose of the invention will be explained by referenceto a particular example of ,its application illus-' trated on theaccompanying drawing, it being understood that this is only arepresentative example.

In this drawing Figure 1 is a plan of the device and Fig. 2 is asectional view taken on the line 22 of Fig. 1.

For laundry purposes, the washed linen is required to be rinsed in watercontaining a determined quantity of blue coloring-matter. By the presentinvention in which a layer of such blue coloring-matter is inclosedbetween two sheets of paper a, b of a blotting-paper texture and soperforated at c that a known quantity of coloring-matter is containedwithin each separable portion thereof, precision can be readily attainedin respect to the degree of coloration of the rinsing water, and wasteand mess avoided.

The protecting sheets of the essential. inclosed-layer of material arerequired to be adherent to one another either through the medium of theinterposed material or otherwise. If the interposed substance is of agummy nature the inclosing and protecting sheets will be suflicientlyattached thereby and, even if it is not, the perforation of two sheetsinclosing a layer of powder. will by the interconnection of the sides ofthe perforations of one sheet with tho-,e of the other unite togetherthe enveloping sheets sufliciently to serve the. purpose of the presentinvention.

Alternatively to relying on the above described inter-connection of theinclosing sheets the interposed layer of essential material may bedeposited in separated patches on one of the sheets which is gummed allover or along the borders of the separated patches, the second inclosedsheet being attached to the first along the said borders, theperforation of the said borders being effected either before or afterthe union of the two inclosing sheets.

Besides roviding a conveniently divisible carrier of lue coloring-matterfor laundry purposes the present invention is applicable to other likepurposes in which to a relatively considerable volume of liquid adetermined quantity of concentrated substance is required to be added.Its employment for dyeing purposes will constitute only an extended useof the invention as above described.

The present invention is adapted to provide also a useful article fordomestic use in culinary operations. The essential interposed layer mayconsist of curry powder for example or other substances adapted toflavor gravies, soups, jellies or the like, or consist of herbs or theessences thereof to boil with vegetables such for example as mint forpeas.

When employed for culinary purposes the inclosing protecting sheets mayadvantageously be composed of wafer-paste or gelatin or a combinationthereof which is adapted to be dissolved with the inclosed essentiallayer in the liquid to be flavored.

The inclosing protecting sheets may carry instructions as to the use ofthe inclosed layer of material, or provide other information.
